Wu Kexin is the childhood friend of Li Muchen's Second Disciple Wang Yang, and also the third disciple (Unofficial).
She is headstrong and possesses a robust will, despite her lacking Spiritual root she vows to keep up with a genius like Wang Yang. Has deep respect for Li Muchen, but also fears his illusive nature.
She hates pork as eating too much of Pork ribs gave her a terrible stomach ache, she enjoys fruits and roaming about the forest without any interventions.
The complicated character of Wu Kexin, this character was originally supposed be a male with a feminine charm, a trap if you will. The characters Wang Yang and Wu Kexin were supposed to mirror Zhao Jun and Li Muchen in theme, but I changed my mind because the number of male characters had far surpassed the female characters, so to strike the balance Wu Kexin became a female, but to keep the boyish parts from before I kept the parted hair (Like Johan Liebert's) in the end.
Also, with Li Muchen around there wasn't any need for another tra-Ahem* what I mean to say is that I didn't want to make the two rivalries identical so I tweaked things which resulted in the current scenario you all know.
Also, If you like the parts where I talk about my ideas and thoughts behind the characters or find it unnecessary, do tell me in the comments.
Think of it as bonus content if you like, it isn't much but yeah
